The government side of your Maine budget

What you pay for Amount Source
Cost to form $175 legislature.maine.gov (we looked on October 2026, so you can too)
Annual report $85 every year maine.gov (we looked on August 2026, so you can too)
Penalty for a late report $50 maine.gov (we looked on August 2026, so you can too)
State fees over three years $345 Lines added together

Your three-year bill from the state is made of the filing fee, the reports due in years two and three, and a yearly minimum tax in states that levy one. Anything the state does not put a fixed price on, a newspaper notice for example, is described but never added.

Notes on the order

Weight 31%: upkeep the price covers. That factor separated the top two.

Maine Registered Agent.co costs you less over three years, but the annual report would still be yours to file.

Include the EIN application and Mainstay Filing passes Maine Registered Agent.co in year 2.

What Maine charges you to form an LLC and what it requires

To form it you need the Certificate of Formation (Form MLLC-6), $175, and an address to send both: the Maine Secretary of State. Every LLC must name a registered agent with an in-state street address.

Official text: legislature.maine.gov (we looked on October 2026, so you can too)

If you skip the service

If you file everything yourself, all you pay is the state: $345 over three years. A service piles $397 to $597 on top for the paperwork and the agent.
